Thus, embryonic ADH can presumably be induced by retinoic acid, further strengthening the argument that ADH plays a role in embryonic retinoic acid synthesis and fetal alcohol syndrome.
These data suggest that the ALD patient defect involves the Fas signaling pathway downstream from the sphingomyelinase and that Fas gene mutations and double-negative T-cell expansion are not the only signs of a defective Fas system.
Downstream of Fas, expression of FADD/MORT1 and FLICE, essential components of the DISC, and negative regulators of Fas signalling including sFas, FAP-1 and Bcl-2, showed no correlation between levels of expression and sensitivity to Fas-mediated cytotoxicity.
More recently studies of non-MHC genes have failed to associate PSC with several cytokine genes (IL-1 and IL-10), with FAS (TNFRSF6), with TGFbeta-1, or with CCR-5 but have found genetic links with MMP-3 and disease progression, whilst the potential role of CTLA-4 gene polymorphism remains in question.
Fas (APO-1/CD95) consists mainly of 2 isoforms, membrane-anchored (mFas) and soluble (sFas), both of which can mediate apoptosis through the Fas-signalling process, not only in normal but also in leukemia T-cells.
The ADH2*2 allele is significantly more common in control individuals, suggesting that it may either confer protection or be a marker for a protective effect against FAS among individuals of mixed ancestry in the Western Cape Province of South Africa.
Known polymorphisms of the alcohol dehydrogenase-2 (ADH2) gene resulting in isozymes with different alcohol oxidizing capacities were investigated as possible candidates for influencing the risk for FAS.

Similarities between patients with fetal alcohol syndrome and with L1 mutations suggest that the mechanism of developmental neurotoxicity of ethanol is partly due to effects on L1 cell adhesion molecule.

To determine whether different alleles of the ADH2 gene (ADH2-1, ADH2-2 and ADH2-3) with differing levels of enzymatic activity can alter the risk of fetal alcohol effects.
Specific inhibitors of both the Fas/tumor necrosis factor-alpha/death receptor pathway and the mitochondrial caspase pathway prevented gp120-induced neuronal apoptosis.
Specific inhibitors of both the Fas/tumor necrosis factor-alpha/death receptor pathway and the mitochondrial caspase pathway prevented gp120-induced neuronal apoptosis.
Peptides NAPVSIPQ (NAP) and SALLRSIPA (SAL), related to activity-dependent neuroprotective protein (ADNP), prevent alcohol-induced damage in a mouse model of FAS.
This model may be a useful tool for dissecting the specific interactions between wild-type p53 and the Fas signal transduction pathway in human cancer cells.
